Module 15 – Database Security Models, Users, and Application Connections

Covers the core topics of the module — including the CIA triad, user roles and permissions, authentication and authorization, and least-privilege principles — serving as a navigational overview that helps learners and instructors understand what concepts will be taught and in what order.

A reading that introduces core database security concepts — including protecting a DBMS from unauthorized access, misuse, and data loss — giving learners foundational context for the security topics covered throughout the module.

A reading that explains how user roles, accounts, privileges, and access-control policies govern who can read, write, modify, or administer a database, helping learners understand how to design and manage permission structures.

A reading that distinguishes authentication (verifying identity) from authorization (controlling access) in database systems, guiding learners through the mechanisms and best practices for implementing both layers of security.

A reading that covers how SQL injection attacks work by mixing user input with query logic, and teaches learners the techniques — such as parameterized queries and input validation — used to prevent them.

A reading that explains how applications establish connections to a database — covering credentials, connection strings, host configuration, and security considerations — so learners can correctly and safely wire applications to a DBMS.

A reading that introduces Object-Relational Mapping frameworks as an alternative to raw SQL, explaining how they abstract database interactions into application objects and the security and maintainability benefits they provide.

A reading that explains why raw database connections are expensive and how connection pooling works — covering pool configuration, sizing, and security best practices — to help learners build efficient, scalable application-to-database integrations.

A duplicate of the Connection Pooling Best Practices reading, covering the same content on the cost of raw connections and pooling configuration, sizing, and security best practices for efficient application-to-database integrations.
